Hi, I'm upgrading my air intake for the z32 uk spec tt. I have been told the apexi is a good choice. Now , from what I believe it is a dry type to stop the oil in these filters wrecking the afm unit.. Does that mean you chuck them out when they are dirty and at £100 or so a touch, seems high, but if that is the price you pay for improved bhp then why not!! What do you wise folks think..apexi or blitz etc...... :D
